  1. Japanese encephalitis in Sri Lanka : comparison of vector and virus ecology in different agro-climatic areas.

    Article - En anglais

    The ecology of Japanese encephalitis (JE) in different agro-climatological areas of Sri Lanka was studied in relation to the abundance of mosquito vectors, infection in domestic livestock, and human infection and disease.

    There was an inverse correlation between altitude and the abundance of potential JE vectors, as well as JE seroprevalence in domestic livestock and in man.

    Little or no JE infection was documented above 1200 m elevation.

    JE seroprevalences in cattle and goats were better predictors of human infection risk than was porcine seroprevalence.

    In areas with asynchronous porcine infection occurring over many months, high overall JE seroprevalence in pigs was found with little evidence of human infection.
